RAILWAY-SWITCH.

SPECIFICATION forming part of Letters Iatent No. 673,596, dated. May '7, H901. Application filed Ianunry 24, 1901. kiei ial No. 44,516. (No model.)

Be it known that we, CONSTANTINE B.VOY- Now and VICTOR ANGERER, citizens of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements cation. I

Our invention has relation to a railwayswitch of the class or type known as tongueswitches,.and in such connection it relates to means for tightening the pivotal connection of the heel of the tongue with the switchrblock, as well as compensating for the wear and tear upon the-pin or boss constituting the pivot for the tongue.

' The principal object of our inventionis to tongue of the switch and the. surrounding complemental parts of the switch-body, together with means for advancing the box or block in the switch-body to bind against the periphery of the pin or boss.

Our invention further consists of a tongue-'- switch constructed and arranged in substantially the manner hereinafter described and claimed. 1 a The nature and scope of our invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which-- Figure l is a top of Fig. 2. Fig. an a side elevational view! "ustrating the interior of onepf the mems of the bearing block or box. Fig. 6 is a in Railway- Switches, {if which the following is a specifi-" Referring to the drawings, switch body,

7 and 8 are horizontal ectional views taken on planes corresponding 0 Figs. 3'and14,respect ively, but illustratinga modified formot' bearing block 'or box; and Figs. 9 and 10 are views similar to Figs. 7 and 8, but iilustrat ,ing a still further modified form-of our invention.

a representsthe in the recess a, of which the tongue I) is adapted to oscillate. In the form of tongue-switch illustrated in the-drawings to which our in veution is pp'lied the heel b the tongue 1) b Upontbe heel b of he tongue b is fornie a pin or boss b switch-body a; and forming the pivot upon which the tongue b is coveredg y-aprotecting-pla e dependirig downward in the .7? is adapted to oscillate.

Th'eswit'ch-body a at the portion wherein the pin or boss 19 is inserted is recessed, and the walls a ofthis recess are preferably upwardly, Between the converging'walls a? of the switch-bodyaand the periphery of the converging.-

pin or boss 1) of the heel b is located a bearing box or block d, adapted to be elevated or lowered in the space between the pin or boss 5 and said walls a, of the switch-body a. The wall of the box or block d is substantially wedgeshaped in cross-seclion, the interior of "the block being rounded to'surro'undthe periph cry. of the pin or boss 11 and the exterior being beveled complementally to the inclined walls a of the switch-body (1,. Upon the periphery of the 'pin or boss 1) is preferably fitted a sleeve or bushing e, of steel or similar hard metal, "ithiu which the pin or boss b is adapted to --urn and which is made to grasp the pin or boss 1) throughout its entire-length. As illustrated, this-sleeve or bushing e is preferably split into two sections, each of which is confined to the periphery e from slipping up or down on said pin orboss. The sleeve or bushing e is connected tothe block or box d, so as to -prevent its turning with the pin or boss 11 by any suitable means,that which is preferred being illusof the pin or boss b by stitute a means when the trated in the drawings as consisting of a lug or lugs (1, formed upon the inner face of the bearing block or boxd and entering a vertically-arranged slot or slots e formed in the sleeve -0r bushing e. -A preferred means of advancing the block or box (1 in the switch-, bod y a, so as to bind against the pin or boss b andits sleeve or bushing e,- consists of a nut f, supporting thebase or bottom of the block or box (1, and a long bolt f traversing the pin or boss b through a holeformed therein and entering the nut f." The bolt f is vadapted to be turned freely within-the pin or, boss Zi -and independently thereof to elevate the nut fand hence to raise or, advance the bearing block or box din the switch-body a. The nut f by preference has a yoke-piece), engaging at its ends suitable slots or recesses f in the bearing block or box d to not only prevent the out from turning, but to also conbolt f is loosened and forced downward to cause the nut fto engage the block or'box d, and thus toforce it downward in the switeh-body In Figs. 2, 3, and 4we have illustrated the bearing block or box as formed of two menibers or sections, and this is'the preferred. construction. The block or box d may, however, be formed of ,t-hrc'e members'o'r sections, as illustrated in Figs. 7 and 8, or offour members or sections, as illustrated in Figs. 9 and 10, or of even a greater number of sections without departing from the spirit of our invention. Q r

For convenience in manufacture we preferably interpose a liner .or lining a between the walls of the switch-body a and the blocks or boxes d, thereby afiording-means to readily center the bearing-boxes and to secure the tongue I) through its pivot orpiu b in proper relative position to the" recess in the switchbody a. This liner or lining may consist of piecesof metalinserted or metal, such as zinc or- Babbitt metal, poured in in a fluid state after the various parts have" been inserted into the switch-body a and temporarily secured in proper relative position by suitable means.

Havingthus described the nature and object of our invention, what we claim as new, and desire to secure. by Letters Patent, is

1. In a railway-switch,-a tongue having a depending hollow pin or boss forming the pivot of said tongue with a switch-body recessed to receive said pin or boss, a bearing block or box interposed between said pin or boss and adjab'ent parts of said switch-body, and means for advancing said bearing block or box in the switchebody to bind said block or box against the periphery of said pin or boss, said means adapted to traverse said hollow pin or boss. 7 p Y 2. In a railway-switch,'a tongue having a depending hollow pin o aboss,asleeve or bushing surrounding said pin or boss and in which said pin or boss is adapted to turn, a swit chbodyarrangedto receive said pin or boss and ing block or said pin or boss and its sleeve, a bearing block or box between said sleeve and surrounding parts of said switch-body, means for advancing said hearing block or box in said switch-body, and a liner or lining interposed between said bear box and switch-body.

3. In a railway-switch, the combination of the tongue having a depending hollow pin or boss forming the pivot for'said tongue, with a switch-body arranged to receive the pin or boss, a bearing-block interposed between the pin or boss and the adjacent parts of the sWitch-body,.a nut supportingsaid bearingblock, and a bolt traversing the hollow pinor boss and turning independently therein, said bolt engaging the nut and arranged to advance the nut and bearing-block in the switchbody to bind the bearing-block against the periphery of the pin or boss.

at; In a railway-switch, a tongue havinga depending pin or boss, a switch-body adapted to receive said pin or boss, a bearing block or box consisting of twoor posed between the'pin rounding portions of theswitch-body, and a liner or lining interposed between said bearing block or box and switch-body,

'5. In a railway-switcm-a tongue having a depending pin or boss, a switch-body adapted to receive said pin or boss, a bearing block or more sections interbox consistingof two or more sections having one of the ends thickerthan the other, said bearing block or box interposed between said pin or boss and switch-body, and a liner or lining interposed between said bearing block or box and switch-body.

6'. In a-railway-switch', depending pin-or boss, a switch-body adapted to receive said pin or boss,'a bearing block or box consistingof two or more sections having thesides not bearing against said pin or boss in the form of a truncated prism or beveled and said bearing-block or box interposed between switch-body.

7. In a railway-switch, a tongue having a depending pin or boss, aswitch-body adapted to receive said pin or boss, a bearing block or box surrounding said, pinjor'boss, and a liner or'lining interposed between said bearing block or box and said switch-body.

v8. In arailway-switch, a tongue having a depending pin or boss, a switch-body adapted to receive said pin or boss, a bearing block or box surrounding said pin or boss, a liner or lining interposed between said bearing block or boss and the sura'tongue having a or box and said switch-body and means for advancing said bearing switch-body'to bindsaid said pin or boss.
